Thanks. > David, IME, it is typically (yet not always) a duplex and/or speed issue between the NIC port and the switch or device it is talking too. man ethtool ethtool eth0 and check to see what speed and duplex are currently in use... if duplex and/or speed are off I typically hard code a *managed* switch and the centos box on whatever ports as necessary by adding this line or one similar to it ETHTOOL_OPTS="speed 100 duplex full autoneg off" To this and other interface files as necessary /etc/sysconfig/network-scripts/ifcfg-eth0 At this point a reboot will take care of it or if you don't want to reboot now, Then I would make a little script called downup.sh ifdown eth0 ifup eth0 and then I chmod 750 that script and then call it like this if from remote ./downup.sh & So I don't lose connectivity... There is probably a more elegant command like way to do that... Be careful if remote box and YMMV - rh
